I have created the attached wheel drawing using the Revolve command.
You will see one cylinder solid thru the wheel on the attached drawing file.
I am trying to use the Subtract command to remove a hole space thru the wheel. Can't get that to work.
Where I am joining 2 solids (like plywood sitting in a dado joint), how can I have one solid be carved out where the 2nd solid overlaps it, without deleting the 2nd solid.
what SUBTRACT does but without the deleting.
Recently have had AutoCAD re installed and and am having trouble unioning and subtracting the two solids in the attached file. Other objects will occasionally subtract and union with these objects, but only occasionally.
View 4 Replies View RelatedI have inventor 2012 and I´m having trouble doing a cut boolean operation to two solids. One is a revolved elipse, so it´s a kind of egg, and the other one is an extruded rectangle.
I want to cut the egg in the rectangular solid, so I can obtain a rectangular solid with an empty egg space inside. I tried to use the "derived" command, so I derived the egg from the rectangular solid, and used the combine command, but with no success. Right now I have two separated solids on the same file (the egg and the extruded rectangle).
what's the best way to subtract one solid from another then turn the remainder into multiple solids?

With 2013 the loft command seems to divide its abilities depending on what type of profiles are selected.
When selecting a closed polyline profile, loft produces a solid. Works fine.
When selecting a region or solid face loft produces only a surface.
The work i am trying to do at the moment involves irregular sections and/created from existing solids.
I could trace the profile and make a polyline, but each profile contains an ellipse, and you cant trace an ellipse.
Where i used to be able to select the ends of the existing solids and create a solid loft,
I now have to produce a section twice (gives you a region), loft the regions, convert the regions to surfaces (because the produced surface doesn't have and faces), union the surface and then convert to solids
Instead of 1 command there are now 6.
I tried turning of the assiciativity (surfaceassociativity 0) hoping that it had some sort of influence but to no avail.
There was no issue with 2010 and 2012 and i have just installed all 2013 products.
I have a lot of work to do and have to produce 3dsolids.
What method will you choose to create 3D solids and surfaces from existing objects in autocad?
View 4 Replies View RelatedI would like to be able to extrude an object then do a subtract or something similer, then somehow put the subtract on a layer so if i hide said layer the extrueded object will be showen as if it never had the subtract applyed. But if the layer is show agean then the extrued will have a hole in it agean.
P.s. for an example of one thing this could be used for, modeling wrenches with difrent shaped grips but the same handle. Without just making multiple copys of the handle.

I am working on a project where I am attempting to design a pendant. I wanted to do this in solidworks but I am not as experience with that and I'm having issues, so I went to what I know, AutoCAD. Unfortunately I am still having problems and I think it has to do with the import file from Adobe illustrator.
What I have is a circle with different parts and block text that I would like to cut out. I saved the illustrator file to a dwg file and it imported with a hatch over all the solid areas. I deleted that to get the respective outlines, and extruded. Most loops extruded but some failed to do so for some reason. But I have an option to convert to a pline, but then I get a specify precision dialog which adds a bunch of points along what seems to be a straight line.
Anyway, when I do manage to get things extruded, and go to perform the subtract command (or intersect which would be faster) I click the main shape, and then click the items I would like to remove, but it doesnt do anything.
I did get one whole to subtract, but I really dont know the difference between that and the others that made it work.
I am beginner at 3D modeling, I have to solids and trying to subtract them. I have done it many time on this particular drawing but for some reason it is not working now. Here is my command prompt

I need to make about 400 selections to Subtract from a box using ProBoolean. Unfortunately it seems you have to select each individual one. Is there an easier way to do this? Essentially, I have a box and need about 400 holes punched through. I am just trying to determine the easiest way.
Right now I have to click on each cylinder one by one after I have arrayed them in order to subtract them. Does ProBoolean have an option to select multiple objects at once to subtract?
How can i use subtract area command in area command while using add command , often it happens we click on polyline whose area we did not want to consider. How can i do like this, i re click on that enclosed polyline and the area gets subtracted and the green fill goes away?

I have an ipart I'd like to create w/ surfaces. The surface color is important because we use that as plate thickness ID in FEA. When I color a surface blue, then another red I continually get the default color when using the mirror or array command. We're creating a customizeable ipart where there will be some intelligence surrounding how big the array (we may need 3, 4, or 5 beams based on the unit size). I need a way that the colors on the surface propogate to the new surfaces created by the commands.
View 1 Replies View RelatedI have a topo map in max, and I'm trying to raise and sink parts of it to make sidewalks and parking lots. My thought was to import line objects from dwg files, shape merge them onto the terrain, change the material number, then extrude. The problem is that shape merge doesn't maintain the correct shape.
I've made sure that I'm in orthographic mode, looking straight down on the surface, but anywhere there's a curve it messes things up. Circles become irregular ellipses. Arcs become more convex or concave. Where I'm shape merging two different objects at different times, objects that had lined up, the curves are now different and they either overlap or no longer touch.
I'm assuming that it's because my terrain mesh is too complex, but I'm not sure how to get around that.
I often work with Civil Engineers and I use line work from Civil programs such as 3D Civil and Bentley MX. These programs give me splines (see image 1). I trace over the lines to create poly surfaces which may end up being grass or concrete etc (see image 2)
I don't use the terrain command because the command is not always suitable. The lines I import often have gaps or other issues thats why I find it faster to trace over the lines to create my poly surfaces.
But if you look at image 2 it's very blocky. I would like to smooth between these surface to make the terrain look more natural. I have played with turbosmooth and meshsmooth but sometimes they screw up the surface or don't work at all.
How I could make my surfaces more natural and less blocky.
I have been trying to figure out if there is a more efficient way of doing this for some time. It seems so basic but it always comes to play in my smoothing process.
For all you more experienced modelers, what is the best way to have the edges and corners stay at their 90 degree angles when smoothing while not compromising the roundness of the surface with artifacting or pinching in the corners. I find this problem when creating extrudes with sharp corners on curved/ round surfaces then smoothing them.
Trying to model a car dashboard, not the wheel or gears but the big shape you hit your knees on if you sit in a car. Following some simple box modeling to get the basic form, apply turbosmooth, add some edge loops to get the right amount of curvature on some edges, great.
I'm miserably failing the next step, which is adding in details like lcd screen and vents. But even something as simple as making a crease that goes left to right across the whole vehicle, since those loops end up breaking the smoothing and the nice subtle curve is gone.
So next I tried geting the basic shape and adding an edit poly modifier on top then another turbosmooth on top of that. But it's getting very out of hand with the amount of faces.
Another idea was putting in the detail first on a flat plane, then using FFD 4x4 to bring the curve back, but then I'm not able to pull out the pieces that came from the box modelling method, how the armrest area comes out from big piece itself.
Am I missing a method of doign this? I don't want to have to resort to just unwrappign it and adding my details with a normal map. I want to use real geometry, and I've seen some great models in the past with this kind of detail, but don't know how to get there.
I am trying to loft 4 circles onto a straight path it seems as if they are turning somewhere in the middle, and the shape ends up looking like several 8:s stacked on top of each other instead of the cone-like shape I'm after.
I've tried aligning the first vertices with the "make first" command, but it didn't work. If I go to subobject level of the lofted object and choose Shape > Compare (as I read in some thread I should..), the pop-up window shows nothing (blank, with the pointer in the middle, doesn't matter how much I zoom).
I am having multiple problems creating a loft. Firstly, it seems as if the "loft" command remembers and uses history of the objects to be lofted, which in my case meant that instead of lofting the scaled down (correct) version of a shape, it insisted on lofting the former, out-of-scale version. It would be great to know if there's a more conveniant workaround to this than redrawing the shapes (as I ended up doing).
Secondly - and this is where I'm stuck now - 3ds will not let me do a loft with the new, redrawn shapes. The loft accepts two of the shapes, but will not let me select the remaining three, claiming that "the shape has a different number of curves than others in the Loft". My question is thus: What should I do to be able to see and edit the number of curves in the shape, so that my Loft will be valid?
I'm going to be creating a 3d visualization for an existing network of gold mining tunnels and ore veins. What I have are scans of 2d hand drawn pages showing mining tunnels and ore veins. There are a couple hundred of these, each representing a 100' thick slice which get progreessively deeper. My intent is to trace these in autocad and stack them up, create solids, import them into 3ds max. One issue is that the ore veins are in some cases continuous from level to level so I'm thinking of using polylines and the loft command to connect the veins between levels.
how to model this efficiently so the import into 3ds max goes smoothly. Or is there an easier way than the acad loft command to model the veins within 3DSMax?
I'm trying to subtract the figure that is attached to union the 3d solids on the "Layer2" layer and subtract them from the 3d solid on layer "Mesh". For some reason I can't do neither.

View 6 Replies View RelatedI have two boxes stacked on top of each other. On the top I have a rectangle which I want to extrude down through the first box and partially through the second box and then subtract the extruded rectangle from the two stacked boxes. Extrude works fine, but when I use subtract it only removes the area from the first box. The bottom box remains solid despite having "extruded" the rectangle down through the bottom box as well.
I've tried joining the two boxes into a single object before using extrude and subtract, but for some reason the join command won't work in this case.
